AT Communication is pleased to announce the expansion of its Tactical range of transceivers with the launch of the Sentry-H™ High Frequency (HF) SDR radio. The Sentry-H™ is built using the field proven Envoy HF SDR architecture. The Sentry-H™ gives operators a secure high-powered software-defined radio designed specifically with rugged mil-spec environmental conditions at a competitive price point.

The Sentry-H™ provides high-power voice and data in a single RF unit. The Sentry-H™ delivers second-generation digital voice, uniquely available customizable frequency hopping, embedded GPS, 3G ALE, and IP/USB connectivity. The Sentry-H™ is suited for both mobile and base configurations without the need for an external amplifier. The system features a smart handset with an intuitive menu system with multiple language options and support for H250 handsets and accessories.

The Sentry-H™ addresses the most important issues for operators of tactical radios — security, reliability, affordability, and ease-of-use.
